I did a search and didn't really find a post that answers my question to the extent that I want it answered.

I've been freezing the milk I pump on the weekends and Fridays. I store in the Lasinoh bags and now it's in our side by side freezer compartment. The BM is taking over the freezer and I want to move it to our deep freezer. How do you recommend storing it? How can I make sure it's cold enough (I'm sure it probably is, but I get paranoid about these things)? Anything else you recommend? Lo is almost 4.5 months. Short term goal: 6 months. Long term: 1 year+.
